摘要： PURPOSE:To increase the flow rate in the pipe and maintain the heat recovery rate high even if the number of heat transfer pipes in the heat transfer panel increases by constituting a heat exchanger of a heat transfer panel that has a plurality of heat transfer pipes that are arranged in parallel, an inlet header, an outlet header, and an intermediate header. CONSTITUTION:In a heat transfer panel 18 a large number of heat transfer pipes 22 are arranged in a gas passage, and the heat transfer pipes 22 are substantially divided into two halves, the left section and the right section. To one end of a heat transfer pipe 22 on the right side (in an area (a)) an inlet header 19 is connected. On the other hand to one end of a heat transfer pipe 22 on the left side (area (b)) an outlet header 20 is connected. These inlet header 19 and outlet header 20 are completely separated, and a gas passing prevention plate 27 is arranged at the position which corresponds to the gap between both headers. And, the other ends 22 of all heat transfer pipes are connected to an intermediate header 25. When the inlet header 19 and outlet header 20 are divided as above mentioned, the gap between the heat transfer pipes 22 (a) and 22(b) becomes large, and the exhaust gas G passes through this gap and makes a short-pass so that the heat recovery rate is reduced. The gas passing prevention plate 27 prevents the short-pass and raise the heat recovery rate.
